[specific embodiment]
Specifically introduce the optimum embodiment of the sublimation purification device of the utility model organic material below in conjunction with accompanying drawing:
See also illustrated in figures 1 and 2, the sublimation purification device of the utility model organic material comprises three quartz glass tubes that are connected in parallel 6, detects and control the control system of quartz glass tube 6, and the impurity removal means 81 that links to each other with quartz glass tube 6, described control system comprises mechanical pump 1, molecular pump 2, vacuum detecting system 3, temperature control system 4, heating system 5 and power control system 7.
Please consult shown in Figure 2 especially, the heating system 5 of heating usefulness is installed around each quartz glass tube 6, this heating system 5 can be a heating furnace, can be resistance furnace also, is used for quartz glass tube 6 is heated so that the impurity distillation of organic material to be purified; In addition, described impurity removal means 81 is cooling water pipes that cooling water is housed, cooling water pipe 81 longitudinally runs through each heating system 5, and quartz glass tube 6 one ends are provided with outlet 61, cooling water pipe 81 relevant positions are provided with import 811, import 811 is connected by pipeline with outlet 61, so, after the gaseous impurity distillation in the organic material of purifying of waiting to distil, go out from above-mentioned outlet 61, then, enter cooling water pipe 81 along the pipeline between outlet 61 and the import 811, the water that is cooled dashes to wastewater disposal basin 9 along cooling water pipe 81.
Further, the utility model device also includes the nitrogen cylinder (not shown) that is connected with quartz glass tube 6, is used for inflated with nitrogen in the quartz glass tube 6, to quicken the cooling in the quartz glass tube 6.
Introduce the concrete steps of the utility model sublimation purification device below with reference to the accompanying drawings:
The step 1) organic material of purifying of will waiting to distil is positioned in the quartz glass tube 6, open cold water switch and make in the cooling water pipe 81 and maintain flow of cooling water, the total power switch of power-on control system 7, then, open mechanical pump 1, quartz glass tube 6 inside are vacuumized;
Step 2) when the vacuum in the quartz glass tube 6 reaches 10pa, opens molecular pump 2 and continue to vacuumize until molecular pump 2 and be in stable state;
The vacuum of step 3) in quartz glass tube 6 is lower than 5 * 10
-3During pa, utilize heating system that quartz glass tube 6 is heated, make the impurity distillation in the organic material;
After the step 4) distillation is finished, stop heating, naturally cooling;
When step 5) is reduced to 50 ℃ when the temperature in the quartz glass tube 6, closure molecule pumping source, mechanical pump, cooling water successively;
Step 6) is opened the nitrogen cylinder valve, to charging into nitrogen in the quartz glass tube 6, to quicken the cooling of quartz glass tube inside, air pressure in quartz glass tube 6 reaches an atmospheric pressure, so, whole distillation purification process is finished, and takes out the sample in the quartz glass tube, and the impurity in it is all removed.
It should be noted that, in the sublimation purification device of the utility model organic material, a plurality of quartz glass tubes 6 are connected in parallel, and the control system that detects and control quartz glass tube 6 has only a cover, so, second quartz glass tube 6 needs heating if first quartz glass tube 6 need vacuumize, at this moment, as long as on power control system 7, click the button that vacuumizes of first quartz glass tube 6, so, vaccum-pumping equipment specifically is exactly that mechanical pump 1 or molecular pump 2 just link to each other with first quartz glass tube 6, thereby, first quartz glass tube 6 is vacuumized; Simultaneously, open the heating system 5 and the temperature control system 4 of second quartz glass tube 6, so, heating system 5 begins the organic material in second quartz glass tube 6 is heated, and by temperature control system 4 adjusting temperature, thus, whole system, can purify respectively according to the progress of different quartz glass tubes, carry out independently of one another, do not disturb mutually, simultaneously, because a cover control system can be controlled at different quartz glass tube 6, therefore, improved the utilization rate of control system, when having avoided vacuumizing, during idle the or heating of heating system 5 and temperature control system 4, the idle phenomenon of pumped vacuum systems takes place.
The above only is a kind of embodiment of the present utility model, it or not whole or unique embodiment, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
